any of us spend thebulkof our day peering at computer screens. Reading this article means there's a good chance you're looking at one right now.

许多人每天都要花费很多时间在电脑屏幕前。比如读这篇文章的时候你就正在看着屏幕。

But does looking at a computer screen damage your eyes? Brisbane optometry professor Nathan Efron does not consider computer screens "harmful" to our eyes.

看电脑屏幕真的会伤害我们的视力吗？布里斯班眼科教授Nathan Efron并不这样认为。

But he admits if you use one a lot, you increase your risk of becoming slightly more short-sighted – where your eyesfocuswell only on close objects while more distant objects appear blurred¹. This is especially the case for children and young adults, whose eyes are still developing.

但他承认如果你经常使用电脑屏幕，会增加你患近视的风险。因为你的眼睛经常盯着近处的物体，远处的物体自然就看不清楚了。这对于儿童和年轻人尤为明显，因为他们的眼睛还没有发育成熟。

In the shorter term, prolonged viewing of a computer screen can make any slight existing vision defects more noticeable. It can also give you what is sometimes known as "computer vision syndrome²" – eye strain, headaches, gritty eyes and blurry³ vision. But this is only temporary and can be minimised by:

简而言之，一直盯着电脑屏幕可以在短期内使视力明显下降。有时候还会让你出现“电脑眼综合症”：眼睛酸痛、头疼、异物感、模糊。但这些都是暂时的，可以用以下方法缓解：

Adjusting the screen display so the contrast is high and the brightness feels comfortable.

调整你的显示器的亮度和对比度，让你的眼睛觉得舒服为准。

Having lighting⁴ that does not produceglareon the screen.

不要让屏幕上出现附近灯光的反光。

Giving your eyesregularrests from looking at the screen (The Optometrists⁵ Association of Australia recommends you do this for five to ten minutes every one to two hours of computer use. It's a good time to make phone calls or do other tasks.)

让你的眼睛定期休息。（澳大利亚眼科协会建议每一到两小时至少休息五到十分钟。你可以利用这个时间打个电话或做些别的事情。）
